My Montero has the 2.6 liter four with a carburetor. My favorite machinist rebuilt the carb before I bought the truck and it runs like a top. Choke works as it is supposed to etc. (Forgive if I insult your intelligence....) Do you know how to operate a vehicle with an automatic choke? First thing to do before starting cold is to push the gas pedal down far enough to set the choke and fast idle....then start it. After it warms up the idle will be racing. At that point tap the gas to let off the fast idle feature.

If its very cold, I pump it a few times before depressing to set the choke and fast idle, then crank. And if it does not start right up I stop cranking and pump it a couple more times.

If you don't do it this way it won't drive worth crapola. So, try it. Maybe your carb is fine.
